The Shimano GRX RD-RX810 is a 2x11-speed rear derailleur engineered for gravel and adventure cycling.
Its SHADOW RD+ system stabilises the chain and minimises cage movement, delivering quiet, precise shifts across demanding terrain. The short cage design suits 11-30T or 11-34T cassettes paired with ULTEGRA, 105, or TIAGRA groupsets. Built on proven RX technology, it offers the reliability and smooth performance gravel riders demand.
